Embodiment Construction
[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0039] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the relationship between the components in a certain posture. If the specific posture changes, the directional indication will also change accordingly.
[0040] In addition, if there are descriptions involving "first", "second" and so on in the...

The invention discloses a multi-channel chip aging system. The system includes: a host computer, an aging power supply connected to the aging device, and an aging device connected to the aging power supply; For the aging chip, one end of the power-on board is connected to the aging power supply; the trans-impedance chip is connected to the other end of the power-on board; at least one chip to be aged is connected to the trans-resistance chip at the same time; the pad fixed in the aging device is the trans-resistance chip fixed on the pad and connected to the pad; shell; shell pins, the shell pins are fixed inside the shell; sockets, the socket is fixed outside the shell, and the socket is connected to the shell pins at the same time. It solves the problems in the existing technology that it is difficult to achieve batch aging of APD chips, aging of APD chips in special packaging forms, and the inconsistency between different pins when the bare chip is directly aged, and realizes the APD of different packaging forms. Chips are aged in batches to improve the accuracy of chip aging effects.
Description
technical field [0001] The invention relates to the field of optical fiber communication, in particular to a multi-channel chip aging system and method. Background technique [0002] The ROSA (Receiver Optical Subassembly) of optical fiber communication is mainly used to convert optical signals into electrical signals. The core components of optical modules are optical transmitting and optical receiving devices. In order to make the designed optical devices perform Stable, the optical device will be charged and aged for a certain period of time before it is officially put into use, so that defective devices and chips can be screened out in advance, and at the same time, the crystal lattice of the chip or device can be stabilized, and the performance can reach a stable state. In the chip aging of optical devices, most of them are emitting optical chips, and receiving optical chips are often not aging for a long time because the overall process is relatively stable. Among the...
